SPECIFICATION forming part of Letters Patent No. 696,806, dated April 1,1902.

Application filed February 11, 1902. Serial No. 93,493. (No model- To(1.5/1 whom, 211; may concern:

Be it known that I, PHILIP T. DODGE, of WVashington, District ofColumbia, have invented anew and useful Improvement inLinotype-Machines, of which the following is a specification.

In commercial linotype machines of the present day-snch, for example, asthe Mergenthaler machine of the general organization represented inLetters Patent No. 557,000-the letter-matrices are dischargedsuccessively from a magazine to an inclined carrier-belt, by which theyare delivered into an assembleror composing device, expansible spacersor justifying devices being delivered into the line at intervals from amagazine above the assembler. When operated by an expert the machinedelivers the matrices and the spacers in very rapid succession, two,three, or more matrices being commonly in the air at one time on theirway to the assembler. It is therefore necessary that the spacers shouldbe delivered quickly and that the interval between their release andtheir entry into the line of matrices shall be accurately regulated withreference to the speed of the matrices, as otherwise they will enterimprop: erly ahead of or behind a given matrix. Experience has developedthe fact that under varying conditions it is desirable to vary the timeconsumed in the passage of the spacers from their magazine to the line.

My invention is designed to secure a variation in this time at will; andto this end it consists in a magazine for the spacers or justifiers somounted that its distance from the assembler or place of composition maybe increased or diminished at will.

The invention also consists in improve ments in the finger-key mechanismfor operating the matrix-delivering devices.

As the other parts of the machine may be of any ordinary orapprovedconstruction, the drawings herein are confined to those partsimmediately associated with my invention.

Referring to the drawings, Figure 1 represents a front elevation of the.composing or assembling mechanism of a linotype-machine with myimprovements incorporated therein.

Fig. 2 is an edge View of the same. Fig. 3 is a cross-section on theline 3 3 of the preceding figures. Fig. 4 is a detail.

Referring to the drawings, A represents the rigid main frame; B, theinclined magazine, from the lower end of which the matrices aredelivered one at a time; Or, the vertical guides or channels throughwhich the released matrices descend; II, the inclined carrier-belt towhich they are delivered, and I the assembler or composing device inwhich the matrices are received and assembled in line side by side.

K represents the magazine for the wedge spacers or justifiers, locatedwith its delivery side directly above the assembler I, so that as thespacers are released they will fall one at a time into the assemblerdireetlybehind the last matrix therein.

In their general construction and arrangement theforegoing parts are thesame as those indicated by like lettersin Patent No. 557,000.

Heretofore the magazine K has been secured immovably in position on theframe, so that the same time is required under allconditions for thepassage of the spacers therefrom to the composed line. I now mount thisbox, as shown particularly in Figs. 1, 2, and 3, so that it may be movedupward and downward on the frame at the Willot the attendant. It may beconnected in any manner which will permit this adjustment; but Irecommend the fitting of its supporting arm or bracket into a groove inthe main frame, as shown in section in Fig. 3, with a bindingscrew Lextended through the slot from the back into the bracket, so that inorder to effect the vertical adjustment it is only necessary to loosenthe screw, move the magazine as required, and then tighten the screw. Bythus raising and lowering the magazine K and changing the distancebetween it and the assembler I am enabled to give a longer or shorterinterval to the passage of the spacers to the line.

The spacers M, of the form generally used in linotype-machines of thepresent day, are suspended by ears at their upper ends on the inclinedside walls of the magazine K, as plainly shown in Figs. 1 and 2, andthey are released, as usual, by lifting them one at a time until theirears rise above the retaininglips at the front of the magazine,whereupon they pass down one at a time through the intermediate guide orchannel to the assembler. The lifting is effected, as shown in theseveral figures, by arms m, carried by a horizontal rock-shaft N,actuated by an arm 0, secured thereto and receiving motion in its turnfrom a vertical bar or reed P, connecting with the keyboard. This rod Pis connected to arm 0 by a-binding-screw Q, so that the point ofconnection may be varied according to the vertical adjustment of themagazine.

For the purpose of imparting motion to the bar or reed P, I extend thesame downward in guides, as shown in Fig. 2, and terminate it just abovethe free end of a vertical pulleyvibrating yoke R, pivoted at r. Thisyoke is slotted to receive a cam S, mounted therein on a pivot and lyingdirectly over a continuously-revolving roll T. The cam by reason of itseccentricity has a tendency to turn down into engagement with the roll;but it is held normally out of engagement by a fixed stop U, whichengages the periphery of the cam, and by a dog V, which normallysustains the end of the cam-supporting yoke, so that the cam is held inan elevated position, as shown.

The dog V,ofangular form,is pivoted in the fixed frame and engages atits opposite end the rear extremity of the finger-key W, fulcrumed at wmidway of its length.

The rear end of the yoke R is cut away slightly in the rear of the pointat which the sustaining-dog V bears thereunder. When, therefore, thefinger-key is depressed at the front end, it acts directly on the dog V,causing its upper end to swing rearward under the cut-away portion ofthe yoke B. This permits the yoke to fall until the cam S is disengagedfrom the stop U and engaged with the roller T, whereupon the friction ofthe latter causes a rotation of the cam, which being sustained by theroller acts to lift the yoke R above its original position, therebyactuating the rod P and causing it to effect the discharge of a spacer Mfrom the magazine K. During this action of the parts the dog Vbeingreleased from the action of the finger-key resumes its originalposition to arrest the descending yoke, the action being insured by aspring W, which depresses the rear end of the finger-key.

As regards the cam, its yoke, and the roller thereunder, the parts aresimilar to those used in the ordinary Mergenthaler machine; but theydiffer therefrom in that the sustainingdogs V are arranged to directlyengage the yoke at one end and the finger-key at the opposite end, thusdoing away with the connections heretofore employed between thefingerkeys and the dogs. The present arrangement is not only simpler andcheaper, but has the advantage of being quicker and more responsive inaction, so that speedy delivery of the spacers is insured. The samemechanism may of course be used for actuating the matrix-deliveryescapements.

Having described my invention, what I claim is 1. In a linotype-machine,a magazine with spacing or justifying devices adjustable to and from thepoint of composition.

2. In a linotype-machine and in combination with the matrix-assemblerthereunder, a magazine for the spacers adjustable vertically, wherebythe time required for the passage of the spacers to the line may bevaried.

3. In a linotype-machine and in combination with an assembler whereinthe matrices I are composed or assembled in line, a magazine from whichthe spacers or justifiers are 1 delivered to the line, means foradjusting said PHILIP T. DODGE.
